Specification of Letters Patent.

Patented Jan. 261 192th Application filed November 3, 1917. Serial No. 200,062.

"a subject of the Emperor of Germany, and

a resident of Sewickley, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Axle-Bearings; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates journal-boxes and more type adapted for use in dustrial railway-cars.

The object of my invention is to provide a the spring-type, and at the same time, do away with the expensive pedestals or guides between which the journal-box is located and adapted to move up and down, providing in lleu thereto axle-bearings or particularly to the connection with inof a very simple and durable form of bearing which can be applied to an ordinary car having a rigid type of bearing without any change in construction.

0 these ends my invention comprises the novel features hereinafter set forth and claimed.

In the drawing the figure is an end view in section of my improved bearing.

In the drawing, the numeral 2 designates the bearing-box which has the space between the axle 3, and the inner face of said bearing-box for the friction-rollers 4 where roller-bearings are employed, although it is adapted for ordinary brassesp The bearing 2 is provided with the wings or extensions 5 projecting out from sides thereof and formed with the strengthening ribs 6 to 've the requisite strength. At each end 0 the wings 5 are the spring seats 7 upon which thesprmgs 8 rest. These springs 8 are interposed between the seat 7 and the inner upper face of the pedestalstrap- 9. This pedestal-strap 9 is preferably in the form of an inverted U, and bolts passing up through openings 11 in wings 5 and through openings in the pedestalstrap and bearing-sill 12, secure the bearing-box to the pedestal-strap and to the bearing-sill. These bolts act as guides for the springs and, at the same time, secure the pedestal-strap and journal-box to the sills of the car. Nuts 13 and 14 at the lower and upper ends of said bolts secure the belts in position, and by tightening up on the nuts 13, it is apparent that the tension of the spring 8 may be regulated.

The outer ends of the wings 5 are recessed as at 15 to receive the downwardly-extending end portions of the pedestal-strap and the end portions of said strap form guides within which the bearing is adapted to move 11 and down and prevent the displacement oi the bearing-box.

By my invention, I provide a simple. and inexpensive form of spring bearing with a small number of parts and only requiring two bolts to hold the same in position, while at the same time, the regular pedestals or guides are dispensed with thereby greatly reducing the cost.

B having the bearing-box held in place by these two bolts, the device can be used in terchangeably with the ordinary rigid type of bearing which is simply bolted to the sills of the car by two like bolts. In this way, any change in the construction of the car provided with the ordinary rigid bearings is KARL H. HANSEN.
